Becoming Your Own Trustee: What Comes Next When You Take Control of Your Trust

For many beneficiaries of significant family trusts, there comes a defined moment — often tied to reaching a specific age written into the trust document — when control changes hands. You gain the option to step in as your own trustee, taking over decisions that were previously made by a parent, a corporate trustee, or another fiduciary.

It is a genuine money-in-motion event. Even though no new money arrives, your relationship to a substantial pool of wealth changes fundamentally. You move from being a beneficiary who receives to a trustee who decides. That shift carries both opportunity and responsibility, and how you handle the transition shapes how well the trust serves you and your family for years to come.

Here is how to think about it.

First, Understand That You Have a Choice — and a Duty

Reaching the age specified in the trust document usually gives you the option to become your own trustee, not an obligation. You can step in, or you can leave the existing structure in place. That decision deserves real thought rather than a reflexive “yes.”

And before you take the reins, understand what you are taking on. A trustee is a fiduciary. If the trust has other or future beneficiaries — children, siblings, or remainder beneficiaries who inherit after you — you owe them duties too. Becoming your own trustee is not the same as the money becoming entirely yours to do with as you please. The latitude you have depends on how the trust is written, and understanding those terms, ideally with estate counsel, is the first step.

This Is a Good Time to Evaluate Advisors

Taking control of trust assets is a natural moment to assess who is advising you — and whether they are the right fit for this next chapter.

This is not necessarily imperative. If you have a strong existing advisor relationship, you may simply continue it. But it is a healthy exercise to get a feel for the lay of the land — to understand what other advisors offer and how they would approach managing trust assets. The questions we have written about for evaluating an advisor apply directly here, with particular weight on experience managing trusts specifically. Ask how many trust relationships an advisor handles, how they coordinate with estate counsel, and how they think about the dual responsibility of serving you while respecting the interests of remainder beneficiaries. An advisor who treats a trust like an ordinary brokerage account is not the right one for this role.

Consider a Co-Trustee in the Early Years

You do not have to do this alone, and in many cases you shouldn’t — at least not at first.

Serving alongside a co-trustee, whether an institution or a trusted professional, can provide valuable accountability in the early years as you grow into the role. A co-trustee adds a second set of eyes on decisions, a check against impulsive moves, and a source of experience while you build your own. It is often a transitional arrangement — a way to take meaningful control without taking on every decision and every risk immediately. As your confidence and experience grow, you can revisit whether to continue the co-trustee structure or move to serving on your own.

Do the Budgeting Work Before You Change Anything

When you gain control of trust assets, there is a natural temptation to change your spending, or to finally move forward with a big purchase or a project you have been waiting on. Resist the urge to act before you have done the work.

This is an ideal moment for a full, holistic budgeting exercise — a complete look at your income, expenses, assets, and goals before any major decisions. Getting everything on paper lets you evaluate a potential purchase or lifestyle change in the context of your entire financial picture, rather than in isolation. The trust may comfortably support what you have in mind, or it may not, and the only way to know is to look at the whole picture first. The money has been there; it will still be there after you have taken a few weeks to plan properly.

More Investment Options Open Up

This is one of the genuine opportunities of taking control. Corporate trustees are, as a rule, conservative and old-fashioned investors. Their mandate is preservation and defensibility, which often translates into portfolios heavy on traditional public securities and light on anything that requires conviction or complexity.

When you become your own trustee — particularly alongside a capable advisor — a broader universe of investment options becomes available. This is a good opportunity to begin thoughtfully exploring private investments: private equity, private credit, real estate, and other strategies that corporate trustees rarely pursue. The key word is thoughtfully. The goal is not to abandon discipline, but to access opportunities that fit your goals, time horizon, and risk tolerance — opportunities the prior structure may have foreclosed by default.

Line Up the Right CPA

Finally, becoming your own trustee usually means you will want a CPA who can handle both the trust’s tax filings and your personal taxes — and the right person matters.

Trusts file their own tax returns and carry their own rules, so you want a CPA with genuine experience in trust taxation, not just individual returns. It is also often wise to find someone closer to your own age, who can grow with you over the decades you will hold this responsibility. Just as important, this person should have a strong working relationship with your wealth advisor. The coordination between your CPA and your advisor — on distributions, on tax timing, on investment decisions with tax consequences — is where a great deal of value is either created or lost. A CPA operating in isolation from your advisor is a missed opportunity.

The Standard to Hold

Becoming your own trustee is a meaningful step — more meaningful than most people appreciate when the date in the trust document finally arrives. Done well, it means understanding the duties you are accepting, evaluating whether your advisor is right for this chapter, considering a co-trustee for accountability, doing the budgeting work before making changes, thoughtfully expanding your investment options, and assembling a CPA-and-advisor team built to serve you for the long term.

Take the time to do it deliberately. The structure your family built was meant to serve you — and stepping into the trustee role thoughtfully is how you make sure it continues to.
